Chemical Structure
Description
6-Methyl-2-(4-(3-methyl-5-oxo-4,5-dihydro-1H-pyrazol-1-yl)phenyl)benzo[d]thiazole-7-sulfonic acid (CAS 5855-99-2) is a high-purity analytical reference standard with the molecular formula C18H15N3O4S2 and a molecular weight of 401.46 g/mol.
Structurally, 6-Methyl-2-(4-(3-methyl-5-oxo-4,5-dihydro-1H-pyrazol-1-yl)phenyl)benzo[d]thiazole-7-sulfonic acid (C18H15N3O4S2) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 13.0, corresponding to approximately 13 ring(s) or double-bond equivalent(s). With a molecular weight of 401.46 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 6-Methyl-2-(4-(3-methyl-5-oxo-4,5-dihydro-1H-pyrazol-1-yl)phenyl)benzo[d]thiazole-7-sulfonic acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
